The guitar-slinging Melbourne muso smashed it out of the park with a livewire rendition of her punchy radio rocker ‘Every Day’s The Weekend’ in front of a packed studio audience and the thousands of yanky nightowls watching from home.

As an added ~kick~, Lahey’s drummer had his bass drum splashed with the word ‘YES’, in an awesome nod back to his homeland and the life-affirming result of this week’s marriage equality vote #LoveWins

Needless to say, Lahey’s American fanbase — which until now included at the very least the band Smash Mouth — has no doubt swelled following the performance.

“I still can’t believe this happened,” homegirl posted on Twitter after notching up the huge milestone. “Thank you so much for having us, @sethmeyers! Never been so happy x.”
